| 摘 要： | Cerospora sojina Hara. toxin produced by mycelia of the pathogen can harm soybean plants.In this paper, 50 varieties and one resistant-susceptible combination were used to study the toxin resistance and it‘s inheritance. Comparing the results from the field under different inoculation conditions, the average coincidence rate of the toxin test is 62.37%. The inheritance of resistance to the toxin of Race 7 of Cerospora sojina Hara was proved to be controlled by a pair of single dominant genes. The toxin appraisal method can be used for many purposes owing to it‘s convenience. |
